Fiesta ST (please don't call it an ST150 - it really doesn't suit - and members of Fiesta ST Owners Club will club you to death!!!

)
However, you'll be a bit hard pushed to get one of these for 9.5K just yet..... more like 10 - 10.5k
As for size... the Fiesta ST has bags of room in it.... I can more or less stand, a little stooped in mine to manoevre mi 15 month old in and out of the back seat!
Its a little car with a lot of heart... and on the track... its absolutely awesome!
